Solved. I change the jquery.min.js with unminified version so i could see more detailed error in browser console. It's datebox with shared-calendar property point to unexisting dom element.
Now it works good
Edited: It seems the bug reappears. I put shared-calendar in main layout and put some datebox input in a tab. When the tab closed the shared calendar also dissapear so when i repon the tab, error above will raise again.
